    - Driver Installer Hi, I have used this newsgroup so far and am able to do this, I have an inf to write an installer for a usb device, so I have SetupCopyInf to copy and update thed river into Windows. Now is there anything else that I can do to improve the user experience when they install our device. There are things like vid,pid, class of device that are mentioned in the newsgroup, but since I am new, I am not sure whether I have to use these or not. Now the way the installer or the four lines of code that I have written works is. 1.You run the installer first, after that when the device is connected, new hardware wizard pops up, you click next there, 2.On the next screen you select a driver from the list of drivers presented 3.Then click next and the driver is finally installed(i think ) and the device is ready to b used. Now I know since the driver is not signed, since its mentioned on the screen 2, maybe we have ge it signed. I have seen that for most installers the screen 1 or for that matter 2 never comes, you run the installer, you see a message that driver is not sined do you still want to install and then click yes there and after installation when device is connected, you dont again have to select the driver that you want to use for your device from a list of drivers available. So maybe I have to use some more functions to do that. All i need is some pointer / suggestion to which functions I can use and will look them up. Thanks a lot Shania Tag: how to detect the location on disk of a file when can't open it? Tag: 39637

    - Reading Audio CD Text Data Anyone have an example of how to read cd text data? I am trying to use the IOCTL_CDROM_READ_TOC_EX command to return CDROM_TOC_CD_TEXT_DATA, but all I have been able to get is various errors: "The device is not ready" and "Incorrect Function" (each error with the same compiled exe but on different machines). Using the same drive handle and same audio CDs I have successfully read Track ISRCs and basic TOC info using IOCTL_CDROM_READ_Q_CHANNEL and IOCTL_CDROM_READ_TOC. What I do is I get a handle to my cd-rom, then I lock the cd-rom drive using IOCTL_CDROM_MEDIA_REMOVAL then I read the TOC from the cd using IOCTL_CDROM_READ_TOC then I loop through each of the songs from FirstTrack to LastTrack in the TOC and I get the ISRC using IOCTL_CDROM_READ_Q_CHANNEL and print it out and get the text data using IOCTL_CDROM_READ_TOC_EX and would print it out if it worked through each iteration. Then I unlock the cd drive. Below is the code I have in C++ that I am trying to use but getting the errors (DeviceIOControl returns FALSE and I get the text of the error with GetLastError()): hDevice is a a HANDLE to my cd rom drive retrieved with the CreateFile function. I know it is a valid handle because I can successfully open and close the cd drive and read the TOC (first & last track numbers and TRACK_DATA items) and read the track ISRCs. I am also curious if anyone knows how I can figure out the size I should specify of the output buffer for this command. Currently I am just setting it to 255 bytes, but don't know if that is enough or too much or what. BOOL getTrackTextData(HANDLE& hDevice, UCHAR trackNum, CDROM_TOC_CD_TEXT_DATA& output) { CDROM_READ_TOC_EX inBuf; inBuf.Format = CDROM_READ_TOC_EX_FORMAT_CDTEXT; inBuf.Reserved1 = 0; inBuf.Msf = 1; inBuf.SessionTrack = trackNum; inBuf.Reserved2 = 0; inBuf.Reserved3 = 0; BOOL bResult; DWORD bytesRet; bResult = DeviceIoControl(hDevice, IOCTL_CDROM_READ_TOC_EX, &inBuf, sizeof(inBuf), &output, 255, &bytesRet, (LPOVERLAPPED) NULL); if (bResult) { printf("Success with %i bytes returned.\n", bytesRet); } return (bResult); } the above function is then called with the following (where i is a loop counter and cdDevice is the cd-rom handle): .... CDROM_TOC_CD_TEXT_DATA trackCDText; bReturn = getTrackTextData(cdDevice, i, trackCDText); .... ps. sorry if this is not the best looking code, I am pretty new to c++ Thank You for any help you can provide.

    - SetPrinterData ERROR_ACCESS_DENIED Hi I am trying to install a windows printer driver uploaded on a RED-HAT 9.0 machine through a samba server. During Installation in the windows client, the setprinterdata function gets called to write the printer setting onto the registry. But here I get an access_denied error. But then I modified the code to open the registry manually and then write to the registry. This works fine. So I if I can still write to the registry using RegSetValue why does SetPrinterData give me Access_denied??? Please let me know if you guys ever had this problem and is there some fix to this behaviour of setprinterdata function.

    - Options for a NDIS-over-USB driver Hi, I am trying to figure out the best (i.e. easiest, fastest and least prone to error; yeah, I know) approach to developing a network driver for a USB-connected network card. From my research so far, I think I can do this in 3 different ways: 1. Remote NDIS - not really an option in this case because the network card has only 64Kbytes of RAM and most of it is used by the device firmware. 2. custom USB + NDIS driver - This seems to be the most complex option. I have written NDIS drivers before but have no experience writing a USB driver. 3. Use an NDIS-WDM driver - write an NDIS driver with a WDM lower edge. I am guessing that this will allow me to use the native USB driver leaving me to focus on the NDIS driver. Am I correct so far? Based on the above, (3) sounds the most promising way to go. If anyone has any other suggestions or comments, please let me know. Thanks, Harshal Tag: how to detect the location on disk of a file when can't open it? Tag: 39616

    - Generating interrupts before my driver is loaded ? Hi All, I have a faulty PCI device which generates faulty interrupts. The device generates interrupts before my driver is loaded. This does not seem to bother WIndows NT 4.0 (probably it does not bother Win2K also). After my driver is loaded and I connect to the interrupt, it emmidiately calls my ISR routine and .... My questions are : *) How come it does not bother windows ? *) What does Windows do, with a PCI device generating an interrupt, before it's driver is loaded ? *) Does Windoes behaviour depend on the PC's HW (PIC/APIC) ? *) Does Windoes behaviour depend on the BUS causing the interrupt ? *) What will happen if the PCI device will cause a faulty interrupt after I Unload/Disable my driver ? *) Does Windoes behaviour depend on the whether or NOT this interrupt is shared ? *) Did Microsoft change it's behaviour between NT 4.0 to Win2k to WinXP ? *) What are the details of what Microsoft does when I connect/disconnect from an interrupt ?

    - Synchronization in filesystem drivers Hi, I am developing a filesystem filter driver, I have it to the point now where I am recording filesystem events by storing them in a queue, which is then processed (and emptied) by a system worker thread. Currently I am recording these events in the dispatch routine, to synchronize with the worker thread I am acquiring a spinlock (which the worker thread also has to acquire). So just a couple of basic questions: The dispatch routine will execute at PASSIVE_LEVEL, right? which means that using spinlocks is perhaps overkill? Can I use some other synchronization object, maybe mutexes, resources or critical sections? This would be better for me because then none of my code executes at DISPATCH_LEVEL whilst the lock is held, and I can work with pagable memory no problems. Assuming mutexes/whatever are OK, do I have any worries using them in a filesystem filter - are there any issues regarding blocking APC delivery - i.e. being alertable/not alertable?? Finally, what would the be the most appropriate sync object? I really can't decide between mutex/event/critical section etc..

    - USB power management problem? Hello, all! While testing recently developed USB measurement device I found a problem with power management that I still can't resolve. Device is single-interface single BULK endpoint device. Device driver is DDK's BULKUSB sample with a couple of IOCTLs added. When the device is plugged into Vitek 2-port USB hub, Windows 2000 crashes (3 machines) with STOP 0x0000001e - KMODE_EXCEPTION_NOT_HANDLED or reboots unexpectedly (old PIII machine), after installation of device driver. With SoftICE installed, a page fault is reported in the driver, with a very strange stack trace, even before the DriverEntry is called. When the device was plugged in the Windows 98 system (by accident), a dialog appeared, saying that USB cannot provide enough power to power the device. Our device reports a maximum consumption of 180 mA, in it's configuration descriptor. Then we've changed this report to 100 mA and the all began to work. Can this be a feature of Windows 2000 power management in that BULKUSB sample does not process gracefully? Thanks in advance, Alexei N.

    - USB device driver installation problem Hello all! I'm expierencing the following device/driver installation problem. We developed a specialized measurement USB device and a BULKUSB-based driver for it. With the most of our test systems installation of device and its driver is not a problem. But with one machine running Windows 2000 Professional + SP4 it turned to hell. When I plug in the device it is detected ('BioSensor USB device', as it's USB string descriptor for device says). Then Device Manager asks for the INF file and I point to the file. And after a second it says that this file contains no information on compatible devices. Setup log (setupapi.log) in the highes verbose level showed nothing useful. The log goes like: .... file bm_usb22.inf opened... .... searching for compatible device ID: usb\vid_71E4&pid_0005&rev_0001, usb\vid_71E4&pid_0005 .... no compatible device ID found (error 0xE0000228) I used NTDDK's usbview to find out if PID, VID and RID were read OK, and it seems they were. (I could also see it from setupapi.log.) Using the REGEDIT I found that device manager creates a node in the registry under HKLM\SYSTEM\CurrentControlSet\ENUM\USB\ with correct VID and PID. This happens on a machine running Microsoft Windows 2000 with Service Pack 4. Problem could not be reproduced on another machine with the same software configuration (i.e. Windows 2000 with Service Pack 4). FYI: KB822831 did not help. Your suggestions? Reinstallation of Windows 2000? Other? Thanks in advance, Alexei N. Adadurov. Tag: how to detect the location on disk of a file when can't open it? Tag: 39515

    - flag settings I want to enumerate a usb2.0 mass storage device. Should I specifically do any setting so that all handles can be closed even if some handles are left open by client? The parent bus driver should be able to close all the handles while usbstor.sys can have any associated handle with it. How am i to do that? pls advise. thank you Tag: how to detect the location on disk of a file when can't open it? Tag: 39498

    - Does anyone know any information on "131 bytes saved through ICF" in mapfile? Hi, I want to automatically generate mapfile and symbol file when building driver, but there are some texts(such as "131 bytes saved through ICF") at the last line of mapfile after building, so mapsym always failed with "Bad hex digit (0x79)" message. Therefore, I have to remove this line manually to generate symbol file. Does anyone know how to solve it? Any ideas would be appreciated.

    - A standard USB driver with bulk transfers? Hi, I have made quite a few USB devices with vendor defined HID pages i.e. the standard HID driver is used. Now a new device calls for bulk transfers. Is there a standard driver I can used for that? Im considering USB modem (CDC class), but one (small) problem is that the virtual COM port is inherently stream oriented. Any other suggetions? Are there other standard drivers could I use? Leo Havmøller. Tag: how to detect the location on disk of a file when can't open it? Tag: 39484

Hi,

We can find file LCN number by calling function FSCTL_GET_RETRIEVAL_POINTERS with a handle to the file, but there are some files can't open because it has already been opend by system, such as pagefile.sys, I know there is a tool(nfi.exe) can do it( It also failed if you just specified pagefile.sys, but will success if you dump all file info on disk. ) Does anyone know how to do?

Thanks in advance!
Polo
